BACKBOARD FOR GAS-STOVES AND FIREPLACES.

To all whom it may concern:

Be it known that I, HENRY ROSAMYER, of Rochester, Beaver county, Pennsylvania, have invented a new and useful Improvement in Backboards for Gas- Stoves and Fireplaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 shows in front elevation a backboard for gas stoves and fire-places constructed in accordance with my invention as applied to a gas stove; Fig. 2 is a vertical sectional View on the line IIII of Fig. l; and Fig. 3 is a plan view of back-board.

The purpose of my invention is to provide a cheap and simple back-board for gas stoves and fire-places which will be very durable, resisting the effect of the alternate heating and cooling to which such backboards are subject, and will efficiently abstract the heat from the flame and communicate it by radiation into the apartment in which it is set.

In the drawings, 2 represents the backboard, which is made of refractory material, preferably of molded fire-clay, although it may be made of iron if desired.

3 is the gas burner, which as usual is set at the base of the back-board. At the lateral margins of the back-board are preferably forwardly projecting flanges 4f, 4:, and its face has forwardly extending projections or prominences 5, 6, which are preferably molded integral with the board, the projections 5 being larger than the projections 6, among which they are interspersed. The gas-flame from the burner passing up along the face of the board engages the middle portions or bodies of the larger projections and envelops the smaller projections. It will here be explained that the short projections 6 are substantially one-half of the length of the longer projections 5, and the burner is located so that the flame will be directed upwardly in a plane intermediate of the length of the longer projections, whereby the shorter studs will be wholly enveloped in the flame so as to heat them to a glowing condition. The larger projections will be heated mainly on the lower side, while the smaller projections being more completely heated will glow and will thus present a very attractive appearance. The

projections at the lower part of the back board being nearer the source of the flame will be more highly heated than those at the upper part, and the heat of the flame will be abstracted thoroughly by the successive action of the projections with which it comes in contact. I may place the smaller projections 6, 6 on the lower part only of the back-board, but I prefer also to place them on the upper part, as this renders the board reversible when desired.

The design and arrangement of the parts may be varied in many ways without departure from my invention as stated in the claims, since What I claim is:

l. The combination with a backboard having forwardly directed flanges at its upright edges, its top and bottom edges being free from flanges, and its front face being provided with substantially horizontal rows of studs and shorter studs interspersed with the rows of studs, the shorter studs being substantially one-half the length of the longer studs, of a burner disposed below the back board in position to direct the flames upwardly in a plane intermediate of the length of the longer projections, said backboard capable of being inverted, substantially as described.

2. A fire-back having its front face provided with substantially horizontal rows of studs, the studs of each row being staggered with respect to the studs of the adjacent row, groups of smaller studs disposed between the studs of each row, the members of each group being disposed one above the other, and the horizontal channels between the rows of studs being free from studs, the upright edges of the back being provided with forwardly directed flanges, and its top and bottom edges being free from flanges, said fire-back capable of being inverted, substantially as described.

3. The combination with a backboard having forwardly directed flanges at its upright edges and its top and bottom edges free from flanges, the front face of the board being provided with substantially horizontal rows of studs, the studs of each row being staggered with respect to the studs of the adjacent row, groups of smaller studs disposed between the studs of each row and substantially one-half the length of the firstmentioned studs, the members of, each group capable of being inverted, substantially as of studs: be disposed one above the other, described. I p 10 the horizonta channels between the rows of In testimony whereof, I have hereunto set studs being free from studs, and a burner my hand. s disposed below the board in position to HENRY ROSAMYER.
